git-multi-pack-index(1)
=======================
NAME
----
git-multi-pack-index - Write and verify multi-pack-indexes
SYNOPSIS
--------
[verse]
'git multi-pack-index' [--object-dir=<dir>] <subcommand>
DESCRIPTION
-----------
Write or verify a multi-pack-index (MIDX) file.
OPTIONS
-------
--object-dir=<dir>::
Use given directory for the location of Git objects. We check
`<dir>/packs/multi-pack-index` for the current MIDX file, and
`<dir>/packs` for the pack-files to index.
The following subcommands are available:
write::
Write a new MIDX file.
verify::
Verify the contents of the MIDX file.
expire::
Delete the pack-files that are tracked by the MIDX file, but
have no objects referenced by the MIDX. Rewrite the MIDX file
afterward to remove all references to these pack-files.
repack::
Create a new pack-file containing objects in small pack-files
referenced by the multi-pack-index. If the size given by the
`--batch-size=<size>` argument is zero, then create a pack
containing all objects referenced by the multi-pack-index. For
a non-zero batch size, Select the pack-files by examining packs
from oldest-to-newest, computing the "expected size" by counting
the number of objects in the pack referenced by the
multi-pack-index, then divide by the total number of objects in
the pack and multiply by the pack size. We select packs with
expected size below the batch size until the set of packs have
total expected size at least the batch size. If the total size
does not reach the batch size, then do nothing. If a new pack-
file is created, rewrite the multi-pack-index to reference the
new pack-file. A later run of 'git multi-pack-index expire' will
delete the pack-files that were part of this batch.
EXAMPLES
--------
* Write a MIDX file for the packfiles in the current .git folder.
+
-----------------------------------------------
$ git multi-pack-index write
-----------------------------------------------
* Write a MIDX file for the packfiles in an alternate object store.
+
-----------------------------------------------
$ git multi-pack-index --object-dir <alt> write
-----------------------------------------------
* Verify the MIDX file for the packfiles in the current .git folder.
+
-----------------------------------------------
$ git multi-pack-index verify
-----------------------------------------------
